Segmentation fault upon a startup

Hmm...

Some tests...
Latest Binary UPX Packed => core dump

Decompressed Binary => runs

Compress Binary again with upx (Version from 23rd Jan 2020) under ArchLinux : All Fine and running.

Maybe broken UPX under Ubuntu?
Do you use 20.04 or 18.04 ?

Edit:

Broken UPX doesnt make sense, because in this case the UPX Package won't run on any Linux....
